UNITED STATES 1 Claim.

My invention relates to a protector for lunch buckets.

The object of my'invention is to provide a fiexible protector fitting snugly on the exterior of a bucket as an insulation for the contents thereof and a shield for the bucket.

A further object of my invention is to provide a resilient protector snuglyfitting on the lower portion of a bucket and having a plurality of horizontally disposed projections simulating bands and to function as a cushion against sudden contact with other objects.

A still further object of my invention is to provide a flexible protector preferably made of rubher to engage snugly about the exterior of a bucket and retained by resilient tension thereon, and removable for application to other buckets.

A still further object of my invention is to provide a flexible rubber protector to receive and envelope the lower portion of a bucket and having an exhaust port to avoid compression during the process of inserting the bucket, the port adapted to normally close itself when compression is released, and the said port to be sealed by the application of rubber cement to avoid intake of air as a further retainer for the shield to the bucket. A still further object of my invention is to provide a protector functioning as an insulator, in which case sponge rubber may be employed, and having a pluralityof recesses arranged for the bottom to avoid direct contact of the entire surface thereof when seated.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of the specification, and in which like characters will apply to like parts in the different views.

Referring to the drawing: Fig. 1 is an elevation of a bucket with my protector applied, and being partly in sectionfor convenience of illustration.

Fig. 2 is an inverted view of theprotector showing the external form of the bottom. T

Fig. 3 is an enlarged fragmentary section of the center portion of the bottom illustrating the application of an exhaust tube insertable'within the exhaust port. 2 1 I Fig. 4 is an enlarged cross section thru onev of the ribs taken on line 4-4 in'Fig. 2. i r

Fig. 5 is an enlarged sectional view modifying the ribs in form with respect to cross section.

Fig. 6 is a modified construction of the wall and bottom of the protector.

To clearly set forth my invention, attention is directed to the specific disclosure in which I PATENT OFFICE PROTECTOR FOR LUNCH BUCKETS James H. Alexander, Staunton, Ill. Application February 26, 1934, Serial No. 713,044

have provided for a dinner bucket 1, a protector comprising an annular wall 2 having a bottom 3, all to engage snugly with the bottom and portion of the side wall of the bucket. The said protector is preferably made of resilient rubber compacted in texture, but not confined to such alone as sponge rubber may be employed and other variations with respect to texture. To avoid excess quantity to accomplish the feature of protection against sudden contact with other objects and additional tension to retain the protector on the bucket, I have provided an annular extension 4 near the top and bottom of the structure,, and a centrally disposed extension 5, all integral with the wall. The bottom has a plurality of ribs 6 radially extending from a disc like extension 7 to an annular portion 8. The last said portion is on a plane withthe centerportion and the outer extension of the ribs, in other words, the body portion of the bottom is depressed at a greater depth adjacent the center portion and diminishing at the plane of the said annular portion 8, by which means the bottom of the bucket is protected by the increased thickness of the bottom portion of the protector, and furthermore a liberal portion of the said bottom is a funnel 11 at the exterior entrance thereof. It

will be understood that when the said protector is applied to a bucket, the wall and bottom snugly engaging therewith, then the tube is removed and the puncture sealed by the .application of rubber cement or the like.

As a modification, I have provided a fiber lining 12 for the protector. The said lining extending over the bottom and side wall upward to a spaced distance from the top thereof, by which means, added insulation is provided, and such other modifications may be employed as lie within the scope of the appended claim, and. having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

In a protector for buckets of the class described, comprising an annular rubber wall having an upper, a lower and an intermediate extension exspaced from contact when the bucket is normally by an inward extension and downward a spaced distance from the point of the upper extension of the wall, by which means the fiber lining is protected against fluid absorption when a bucket is placed within the said wall.

JAMES H. ALEXANDER.
